Meet Charlotte Hajer

Through Arc & Measure, I help mission-driven organizations align heart with evidence. I provide strategic planning, grant management, impact evaluation, and storytelling services grounded in human-centered practice and rigorous analysis. Whether you need a grant proposal that brings in revenue, a strategic plan that aligns your organization with a changing social and political landscape, or compelling data that showcases your work, we help you hone your story and turn your purpose into measurable results. Whether we’re crafting stories or analyzing quantitative data, our approach is always human-centered: our primary goal is to honor your team’s passion and your community’s voices.

Trained as a social science researcher, I came to the nonprofit sector as a grant writer in 2011. Since then, I’ve worked with organizations across the Northern California Bay Area, honing my skills in nonprofit strategy, fundraising, evaluation, and storytelling to grow agency budgets, build capacity, and boost operational effectiveness. Over the past 14 years, I’ve helped agencies raise a total of over $25 million to fund their transformative missions. I’m deeply curious about what drives human experience, and committed to social justice. Originally from Amsterdam, the Netherlands, I’ve lived on three continents and now reside in California wine country with my husband and two sons. I hold a BA in Human Development from the University of Chicago, a PhD in Medical Anthropology from the University of California, San Diego, and a certificate in nonprofit management from the University of the Pacific.
